molecular weight compounds with two and three rings were the
most predominant PAHs in all of the species. The detected
concentrations in L. gahi (from the Atlantic Ocean) may mean
additional carcinogenic risks for high cephalopod consumers.
Moreover, in a survey that revealed the measurable presence of
four low molecular weight PAHs (naphthalene, acenaphthene,
fluorine, and phenanthrene) in three commonly consumed and
commercially valuable fish species (sardine, chub, and horse
mackerel) from the Atlantic Ocean, naphthalene was the most
abundant PAH in sardine and horse mackerel, accounting for
ca. 55% of the total PAHs.41
